Share Library between UWP App and .NET Core

Question

What is the best practice to share a library (also C# project) between Windows UWP app and a .NET Core web app?

I have the following solution setup starting from scratch:

• Solution
  • UWP App
  • Lib (With functionality I want to use in both other projects.)
  • .NET Core WebApp (2.2 or maybe 3.0)

As far as I could figure out, the only solution is, to create two projects for the lib, which share the same .cs files. But this feels a bit like a workaround and I am looking for a "clean(er)" way.

Answer 1

You can share a .NET Standard 2.0 library between those projects, see Microsoft's documentation.

Note, that you cannot use any classes specific to .NET Core or the UWP in such a project.
